master onion corporation has a target capital structure of 30 percent common stock, 4 percent preferred stock, and 66 percent debt. its cost of equity is 18 percent, the cost of preferred stock is 6.5 percent, and the pre-tax cost of debt is 8.5 percent. what is the firm's wacc given a tax rate of 21 percent?
The firm's WACC is 6.7% for such a specified tax rate of 21%, according to the stated statement.
What does "debt" mean?Debt may be defined as the sum that the borrower owes the lender. A debt is an amount of money that has been borrowed for a set time period and must be repaid, plus interest. The borrower's creditworthiness affects both the debt's size and its acceptance.
Briefing:Given,
Ke = Cost of equity (18%)
Kp = Cost of preferred Stock (4%)
Kd = Pre Tax Cost of debt (8.5%)
Wk = weight of equity (30%)
Wp = weight of preferred Stock (4%)
Wd = weight of debt (66%)
t = Tax rate (21%)
WACC = (Cost of equity*weight of equity) + (Cost of preferred Stock * weight of preferred Stock) + (Pre Tax Cost of debt*(1-Tax rate)*weight of debt)
WACC = (0.18*0.30) + (0.04 * 0.04) + (0.085*(1-0.21)*0.66)
WACC = (0.18*0.30) + (0.04 * 0.04) + (0.06*0.79*0.25)
WACC = 0.054 + 0.0016 + 0.01185
WACC = 0.06745
WACC = 0.067
WACC = 6.7%
Therefore, with a specific tax rate of 21%, the company's WACC is 6.7%.
